We discuss the dynamic bandwidth allocation schemes in TDMA uplink channel of satellite networks. And a scheme based on max-min fairness is discussed and implemented in Tdma-bod simulator of ns-2. Simulation results show that this scheme can improve the throughput and delay performance and provide better QoS for satellite system. And in future network scenario that including more burst traffic and...
Multi-hop wireless networks (MWNs) are a promising technology for releasing the vision of pervasive communications, e.g., providing communications in remote areas without telecommunication infrastructure. In MWNs, the channel resource is efficiently managed by proper spatial reuse. One of the Medium Access Control (MAC) protocols with such characteristic is Spatial TDMA (STDMA). In addition, STDMA...
Major design issues in Wireless Ad Hoc Networks is the design of the routing algorithms and the Medium Access Control (MAC) protocols. Spatial TDMA (STDMA) is a ldquoconflict-freerdquo MAC protocol for these networks, thus enabling high spectral utilization. In link-oriented STDMA, the schedule specifies when particular radio links will be activated. Moreover, the use of power control and heuristic...
